Is Your Roof Ready for Winter?

Prepare Your Roof for Winter Weather

Winter has arrived and last week we received our first batch of winter weather; today I’m watching the flurries as they fall. Cold temperatures, windy conditions, heavy precipitation and snowfall can create various winter roof problems and we at Integrity Roofing and Construction want you to be prepared and know what to look for on your roof.

Common Winter Roof Problems

  1. Tripping Hazards

    • Missing Shingles: Swift replacement of missing shingles is crucial for preventing water damage, especially if your roof lacks underlayment or has compromised underlayments.
    • Cracked or Torn Shingles: Openings in shingles allow moisture intrusion, leading to potential roof deck and attic damage.
    • Curled Shingles: The precursor to cracked or missing shingles, curled shingles are vulnerable to wind damage.
    • Damaged Flashing: Cracked flashing at vulnerable roof points can enable water infiltration, potentially causing chimney damage.
  2. Slippery When Wet

    • Bald Shingles: Loss of roofing granules not only reduces traction for walking but also exposes the roof to UV rays, potentially leading to damage.
    • Moss: A potential slippery hazard that, if left unchecked, can accumulate moisture and cause damage during freeze and thaw cycles.
    • Ice Dams: Blockages formed by ice along the eaves can induce water pooling and subsequent leaks.
  3. Snow Coverage Matters

    • Efficiently covered snow on roofs indicates optimal roofing system performance and serves as a suitable landing spot for Santa’s sleigh. Proper insulation and ventilation play key roles in controlling snowmelt and ice dam formation.

The Role of Insulation and Ventilation

  1. Insulation: Adequate insulation in attics helps prevent heat loss during winter and heat transfer in summer, minimizing excess snowmelt.
    • Batts and Rolls: DIY-friendly installation between floor joists and wall studs.
    • Blown-In Loose Fill: Utilize an AttiCat® machine for easy installation and proper ventilation by adding baffles to soffit areas.
  2. Ventilation: Balanced air flow, facilitated by intake and exhaust vents, is crucial to prevent attic heat and moisture buildup. Proper intake and exhaust vent balance ensure efficient airflow.

Winterizing Your Roof: Key Steps

  1. Check the Gutters: Ensure gutters are free from clogs to prevent ice dams and water pooling around the house foundation.
  2. Inspect Attic Space: Verify proper ventilation and insulation to prevent irregular air distribution and subsequent structural damage.
  3. Missing Shingles and Granules: Promptly replace any missing shingles and assess for worn granules to maintain roof integrity.
  4. Roof Cleaning: Prevent microorganisms like moss, lichen, and algae from causing significant roof damage by cleaning and adding zinc stripping.
  5. Detect Leaks: Inspect both interior and exterior areas for potential roof leaks and address them promptly.
  6. Trim Branches: Prune nearby branches to prevent potential roof damage during high winds or snowfall.
  7. Check for Sagging: Address any structural issues, such as roof decking sagging, before heavy snowfall to prevent collapse.

Maintenance Tasks for Winter Preparation

  1. Repair Damaged Shingles and Flashing: Attend to missing or damaged shingles and flashing to prevent leaks and water damage.
  2. Replace Old Caulking: Upgrade caulking around vent pipes and chimneys to ensure proper sealing against water intrusion.
  3. Trim Trees: Prune overhanging branches to prevent potential roof damage during snow or ice storms.
  4. Improve Attic Ventilation and Insulation: Enhance attic airflow and insulation to prevent ice dam formation.
  5. Clean Gutters and Downspouts: Remove debris to prevent clogs that may lead to ice dams.

Winter Predictions and Roof Maintenance

As winter approaches, considering weather forecasts is essential. Performing regular roof inspections and maintenance during fall can mitigate potential moisture-related damages, preserving the roof’s longevity.
